Danfoss VLT 2800 Series Operating Instructions Manual page 90

Safeguards:
• Electronic thermal motor protection against
overload.
• Temperature monitoring of the power module
ensures that the frequency converter cuts out
if the temperature reaches 100 °C. An over-
load temperature cannot be reset until the
temperature of the power module is below 70
°C.
• The frequency converter is protected against
short-circuits on motor terminals U, V, W.
• If a mains phase is missing, the frequency
converter will cut out.
• Monitoring of the intermediate circuit voltage
ensures that the frequency converter cuts out
if the intermediate circuit voltage is too low or
too high.
• The frequency converter is protected against
earth fault on motor terminals U, V, W.
